CTF Cosmic Blog (Astro + Tailwind + MDX)

A static, GitHub-Pages-friendly personal site for CTF posts, research notes, and link posts — with a cosmic/astronaut theme.

If you want to find older challenge writeups that were written before this website existed, check the Notion workspace:

Quick start

npm install
npm run dev

Build locally:

npm run build
npm run preview

Writing content

Content lives in:

• src/content/blog/*.mdx
• src/content/links/*.md (external link posts)

Each file has frontmatter (see sample posts).

Deploy to GitHub Pages

This project uses GitHub Actions (see .github/workflows/deploy.yml).

1) Enable Pages

Repo → Settings → Pages → Build and deployment → Source: GitHub Actions.

2) Configure base path

This site supports both:

• Project Pages: https://<user>.github.io/<repo>/ (default)
• User Pages: https://<user>.github.io/

The Astro config auto-detects the repo name in GitHub Actions and sets base accordingly. For User Pages, set repository name to <user>.github.io OR set BASE_PATH=/ in the workflow env.

3) Push

Push to main. The workflow will build and deploy.

Customize

• Edit src/config/site.ts for your name, bio, social links, and site URL.
• Replace public/astronaut.svg and public/og-default.png if desired.
